These calendar based pages
provide a listing of those GOES Data Collection Platforms whose raw
data messages were flagged by the Wallops Island GOES Data Collection System
(DCS) as having transmission errors and the times they occurred.

All DCP messages that
HADS attempts to decode, and contain a parity error, are logged onto these
pages.

The exact error was not
identified by the facility, but the DCS determined that at least one bit
of data was corrupt. A parity error indicator flag was
set by the DCS system and encoded into the raw data message.

This is how the HADS decoder
handles the DCPs with parity errors. If the corrupt raw data message
was still decodable by the HADS processor program, HADS acknowledged
the parity flag and set the SHEF encoder to append the 'parity error' Data
Qualifier Code to each data value associated with the questionable raw
data stream.

If the raw message was
contaminated to a greater degree, then it may not have been decoded at
all by HADS.
